NAME
Class::Meta::Types::Perl - Perl data typesSYNOPSIS
package MyApp::Thingy; use strict; use Class::Meta; use Class::Meta::Types::Perl; # OR... # use Class::Meta::Types::Perl 'affordance'; # OR... # use Class::Meta::Types::Perl 'semi-affordance'; BEGIN { # Create a Class::Meta object for this class. my $cm = Class::Meta->new( key => 'thingy' ); # Add an integer attribute. $cm->add_attribute( name => 'my_hash', type => 'hash' ); $cm->build; }
DESCRIPTION
This module provides Perl data types for use with Class::Meta attributes. Simply load it, then pass the name of one of its types to the "add_attribute()" method of a Class::Meta object. See Class::Meta::Type for more information on using and creating data types.The validation checks for Class::Meta::Types::Perl are provided by the Class::Meta::Type's support for object type validation, since Perl data types are understood by "UNIVERSAL::isa()".
The data types created by Class::Meta::Types::Perl are:
- scalar
- A simple scalar value. This can be anything, and has no validation checks.
- scalarref
- A scalar reference. "UNIVERSAL::isa()" must return 'SCALAR'.
- array
- arrayref
- A array reference. "UNIVERSAL::isa()" must return 'ARRAY'.
- hash
- hashref
- A hash reference. "UNIVERSAL::isa()" must return 'HASH'.
- code
- coderef
- closure
- A code reference. Also known as a closure. "UNIVERSAL::isa()" must return 'CODE'.
